Lenovo IdeaPad 720S 13IKB

Basically, the looks of the 720S 13IKB inherit many similarities with the previous IdeaPad lines in minimalist style, limiting the extra details but still ensure aesthetics. The casing is made of solid metal, including the area around the keyboard and the palm rest. The edges are beveled to the maximum, sharp work, square short. Yellow champagne covers the entire body, making it more elegant and resistant to stains or sweat.

The whole upper surface of the machine almost without any decorative motifs but simply sprayed smooth paint. The Lenovo logo, as usual, is sloped to the left with a modest, well-polished, color-coordinated chassis that barely recognizes the brand. The machine is lightweight with a weight of only 1.1Kg with a thickness of only 13.6mm, easily folded in a backpack or handle by hand and very convenient to move. This is also one of the thinnest 13-inch laptops on the market today.

Solid metal material also helps the 720S 13IKB to be sure, seamless connectivity required in a high-end laptop. There is not any loose. Hinged which extend up to 180 degrees for flexible viewing angles. The underside features slippery rubber feet and a large heat sink that promises efficient heat dissipation. The minus point in the design of the laptop from Lenovo is that opening the screen is difficult because there are no edges at the edges to create a fulcrum. The edges of the machine are also cut diamonds slightly sharp.

Lenovo eliminates almost all of the popular connectivity ports such as HDMI, memory card reader, and retains only two USB 3.0 Type A ports (one for charging peripherals for external devices. both off) and two USB Type C ports, alongside the combo mic and headphone jack. Noteworthy, a Type C USB port supports both Thurderbolt 3 and up to 40 Gbps, allowing simultaneous transmission of data, images, and audio, connected to up to two 4K monitors, and fast charging. Having a Thurderbolt 3 port means you can use graphics solutions that are removable from the eGPU to boost graphics performance when needed, or connect to extended dock ports for additional peripheral ports. One USB Type C port remains available as a power port (with USB 3.0 support), and the included charger also uses this convenient connector.

Monitor, sound, webcam

The thin bezel trend is widespread on smartphones and the latop also can not stay out of the game. With the IdeaPad 720S 13IKB, the sides are pretty thin and the upper edge is just a bit thicker. The screen surface is pushed close to the border to make the image more vibrant, spacious, and more effective when browsing the web and more clearly when watching movies, playing games. 13.3-inch, Full HD resolution, IPS panel for sharpness, good detail.

The colors in the direction of a glistening, eye-catching, warmth is warm color suitable for watching movies, playing games but when needing to adjust the image with high color accuracy, you should calibrate again. Screen for deep black, high contrast, low light, wide viewing angle. High screen brightness, good viewing even when outdoors, anti-glare panel effectively reduces glare from the light source directly to the screen.

One point to note is that by default, the integrated graphics card driver from Intel automatically shuts down its brightness when it enters some darkly-colored app to save battery power, so it can be annoying to turn it off. Go in settings if you want the most stable brightness. The screen does not support touch so you do not try to touch to avoid affecting the display quality.

The sound of the machine is noticeable with the JBL pair of speakers, integrated with Dolby Atmos technology. The speakers are arranged on the underside, the size is quite large, the sound straight down the table and create a pleasant effect. Speaker for loud volume, clear. Dolby Atmos technology is activated through the built-in software to make the sound more alive, more prominent, recreating pretty bass, treble, automatically optimized for each situation watching movies, listen to music, play game or video call. If you want, you can customize the Dolby sound effects to your liking.

On the webcam, the point is praiseworthy thin but the camera on the IdeaPad 720S is placed in the upper position, not moved down the bottom or the hinges as some thin notebooks so the angle for natural, easy align. Webcams are relatively small in size, perhaps to fit in a thin bezel. HD resolution (1280 x 720 pixels), 30fps frame, fixed focus, medium quality, sharpness, details are good but slightly shiny. The picture gets darker than the actual pretty much. In return, the recording microphone of the machine works quite well, effectively filtering noise, clear sound, clear ambient noise around a lot of noise.

Keyboard, touchpad, fingerprint

Lenovo laptops have always been appreciated for the keyboard thanks to good typing, bouncing, and proper keyboard layout. On the IdeaPad 720S 13IKB, this continues to be promoted. Although the size of the body is very thin but the keyboard is still good for the journey, bouncing keys, sticking hand, only when the fast typing is slightly text and the navigation keys up and down slightly small. The flex phenomenon when strength press is limited is good. Text on sharp keys, beautiful fonts, spacious keyboard, convenient operation.

The power button follows the style of most lightweight laptops today when combined with the main keyboard rather than separate. This button is also slightly dented to prevent users from making a mistake. One note is that Lenovo has tweaked the power button and asked to hold it to sleep, instead of simply pressing a button like the normal power button.

Backlit keyboard with 2 different brightness. Backlight is printed directly on each key, not just on the edge, giving high brightness, clarity, beautiful appearance, easy operation when working at night or low light conditions without turning on table lamps. The default F keys will be used to control the volume down, screen brightness, fast off the touchpad, and so on. To use F1, press F2 to hold the Fn key. For refinement, users can use the built-in Lenovo Vantage software without the need for a BIOS update.

Touchpad is also made of large size, spacious, covered with glass, for high sensitivity, smooth, no hitting. The touchpad supports the Microsoft Precision driver, allowing for a smoother, more granular, zoom operation on the Edge. If you only use office tasks, basic photo editing, touchpad on the 720S can completely replace the mouse outside.

For enhanced security, the 720S features a touch-sensitive fingerprint sensor that supports Windows Hello. The layout of the fingerprint sensor in this position is more reasonable than putting the same touchpad as some other laptops do. The fingerprint sensor responds quite fast, recognizes the many fingerprints but the unlocking effect of Windows 10 is still a bit cumbersome compared to the current smartphone. In addition to logging in to Windows, you can also use your fingerprint to log in to a number of websites or software such as Dropbox, which is faster and more convenient than entering a traditional password.

Hardware is pretty good with the 8inch i8-8550U or i5-8250U (i5-8550U or i5-8250U) Inel Core processor, 8GB of DDR4 memory, Intel UHD Graphics 620 integrated graphics. Built-in Windows 10 Home, the point worth more than the IdeaPad 720S 13IKB is probably a 256GB NVD-style PCI Express SSD, for data transfer rates twice faster than conventional SATA SSDs. This is reflected in the boot speed, shutdown, open the application is very fast, respond almost instant, no delay. The hard disk speed measured with Crystal DiskMark 6.0 software is also impressive.

The Intel Core i5-8250U processor is also a significant upgrade, with up to 4 cores (1.60 GHz, 6 MB SmartCache, Turbo Boots 3.40 GHz), compared to only two cores of the Intel Core i Life 7 (Kaby Lake) before.

The scores from the Geekbench 4 and Cinebench R15 software rated CPUs show that the single-core performance of the i5-8250U was a little higher than the i5-7200U and was comparable to the i7-7500U. While multi-core performance outperformed, 60% more powerful than the two popular CPUs of the previous generation. In fact, the Intel Core i5-8250U on the IdeaPad 720S does the job well, including heavy tasks like editing, editing, exporting files in Lightroom or Premiere Pro. 8GB of DDR4 RAM also offers good multitasking performance, which can open multiple apps in parallel without distortion, lag.

The Intel UHD Graphics 620 integrated graphics on the Coffee Lake chips is similar to the Kaby Lake, so it’s no surprise that graphics performance is not significantly different. You can play lightweight online titles like The Secret Alliance, Fifa Online 3 with moderate graphics settings at Full HD resolution. But any heavier titles like PUBG, PES 2018, Fifa 18 are too much for the machine.

The temperature and noise levels of the IdeaPad 720S are good. The machine runs smoothly, even when it comes to heavy load, CPU, GPU running at 100% capacity. The efficient heat sink, in addition to the large heat sink under the bottom, also has two small heat sinks in the hinge area to keep the machine running at high frequencies for long periods without overheating.

One note is that the upgrade capacity of the machine is almost zero, all components are hard soldered onto the board and can not be removed by hand, not even RAM or SSD.

Battery life, software

About software, Lenovo does not install too many “bloatware” applications on the machine. Only the Lenovo Vantage app comes pre-installed with a pretty, modern interface that blends seamlessly with the Fluent Design theme on Windows 10. In addition to fine-tune keyboard and touchpad settings, Lenovo also manages the Set the screen, battery, sound, network connection, such as automatically reduce the screen brightness when locking the camera or turn on the eye protection mode night … This application has the feature of error checking. the hardware, software in the machine, automatic driver updates, software system is quite useful.

The other application is Lenovo App Explorer will give suggestions about the app, the game needed, interesting for users to conveniently refer, explore.

About the battery life, equipped with 46 Wh battery, the actual battery life of the IdeaPad 720S is not really impressive. With common tasks such as web browsing, text editing, lightweight photo editing, 70% brightness screen, setting in Balance Better Performance mode in Windows 10, the machine can only hold about 4 to 5 continuous use. Convenient is the USB Type-C port of the charger so you can use it with backup batteries that support USB Power Delivery or a compatible smartphone charger or USB Type-C port on some monitors computer.

The included charger has a capacity of 45W and takes about 2½ hours to fully charge the device from 10% of the battery. The charger is quite cool when in operation and the machine does not have much warming up when used just as charging.

Summary

The Lenovo IdeaPad 720S 13iG has a lot of attractive features compared to competitors in the same segment, such as high-speed PCIe NVDe SSD, Thurderbolt 3 modern port, large RAM, fingerprint sensor. Solid metal design, eye-catching, high-end, lightweight. The screen is thin, bright, sharp, opening angle of 180 degrees. Keyboard, touchpad are good quality.

The restriction of the product is that there are few connections, especially the memory card reader and HDMI port is still very popular. It’s also hard to upgrade hardware, and the battery life is not impressive.
